Computed Tomography

4.4K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Area of Science:

  • Veterinary Medicine
  • Genitourinary Imaging
  • Comparative Anatomy

Background:

  • A case of suspected cryptorchidism (undescended testicle) in a Reeves' muntjac deer (Muntiacus reevesi).
  • Initial physical examination and sonography failed to locate the presumed undescended testicle.

Purpose of the Study:

  • To investigate the utility of contrast-enhanced computed tomography (CT) in diagnosing cryptorchidism in a non-human mammal.
  • To avoid invasive exploratory surgery for cryptorchidism diagnosis.

Main Methods:

  • Contrast-enhanced computed tomography (CT) imaging was employed to visualize the abdominal cavity.
  • Diagnostic imaging was performed to locate the undescended testicle.

Main Results:

  • Computed tomography (CT) imaging did not reveal the presence of a cryptorchid testicle.
  • The final diagnosis was singular testicular anorchia (absence of one testicle).

Conclusions:

  • Contrast-enhanced computed tomography (CT) may be a valuable, non-invasive tool for diagnosing cryptorchidism, even when other methods fail.
  • This case highlights the potential utility of CT in veterinary diagnostics for genitourinary anomalies.
